   ADR-004 (plain CSS, no framework) · ADR-006 (identity: consistent with CGP-07 of
   Oglasna-Deska.SI, not equal — same ink, frame and pin; cobalt instead of cinnabar).
   Lines instead of shadows; one accent; light and dark scheme (system or explicit choice).
   Motion: loops run only with JavaScript (so the pause control exists) and never with
   prefers-reduced-motion. Baseline: browsers released since 2025-01-01.
